D. 0.07. the negative exponent which is two indicates the number of zeros in the standard form. and the 7 indicates the first number in the standard form
2x-y=8...(1)
x+y=7....(2)
from (2)
y=7-x....(3)
put (3) into (1)
2x-(7-x)=8
2x-7+x=8
2x+x=8+7
3x=15
x=5.....(4)
put (4) into (2)
x+y=7
5+y=7
y=7-5
y=2

To find the area of each backyard, we need to multiply the length and width together.
For Branda, her yard is 35 by 90, which means the area is 35*90 which = 3150.
For Laurie, her yard is 40 by 65, which means the area is 40*65 which = 2600.
Now, we are asked to find the difference between Branda and Lauries yard areas. The difference means how much larger Branda's area is than Lauries.
This means we have to subtract Laurie's area from Branda's.
So, we do 3150 - 2600 = 550
So, our answer is 550ft^2
In order to accomplish that assignment, you might suspect that a person
needs to know something about the figure ... things like maybe what shape
it is, and what a few of its measurements are. You would be absolutely correct
too. I've looked over your question, and found that you haven't included a single
shred of information about the figure. I don't know if it's a square that can fit in
the bottom of my coffee cup, or a circle that the Earth can fit through. If I see it
walking around on the street tomorrow, I won't even recognize it. Although I do
crave to solve the problem and answer your question, I have nothing to get to
Square-1 with. I'm sitting here at Square-0 , looking for information to use in
my calculations.
